Application filed November- 16 1921-. Serial is. 515,465.

This invention relates to an improvement in wheels, particularly topressed steel wheels of the disc type. V

In our oopending application, SerialNo. 344,282, filed December 12,1919, there is dlsclosed a standardized or universal Wheel in the use ofwhich a tire may be changed alone, or with its rim as a unit, or withits rim and the wheel body as a unit, and which eliminates the necessityheretofore existing for the manufacture of numerous sizes of threedistinct types of wheels, and possesses numerous other advantagespeculiar to itself., lhe main ob ect of the present invention is theproduction otan'improved Wheel;

of'this standardized or universaltype, pos sessing the furtheradvantages ot fewer parts, increased lightness, particularly rimincreased resiliency, increased lightness, accessibility, faster andeasier r1m operation, better vibration control, and lower" With this andother objects not cost. specifically mentioned in view, the inventionconsists in certain constructions and combinations which will behereinafter fully described and then specificallyset torthin thecla-imshereunto appended.

In the accompanying drawings, which form a; part of this: specificationand in which like characters of reference indicate the same or likeparts, Fig. 1 is a cross sectional view of a wheel constructed in:accordance with the invention; and: Fig. 2 is a. -fragmentary detailside view showing one of the vibration control devices shown in Fig. 1 l

Referring to the drawings, which illuse trate but one or many possibleconcrete em.- bodiinents of the invention, 5 indicates a hubprovidedwith a disc mounting flange 6 the outer face or" which lies behindtheplaneoft. impact indicated by the line PI- in Fig. 1. The purpose of so.locating the hub flange is to give the Wheelas'a whole a dish ofapproximately two: degreesv whereby itisv strengthened: against. lateralstresses developed in road use.

Mounted on'the hub 5 is a disc which, as shown, has a central fiatmounting section- 7' curved into a retreating, conical mid-section 8,both beingbehind the plane of impact,

The mid-section curves: into a concavoconjvex rim section which crossesthe plane;

ofimpaet at 10"andarecrossestl esame at 1 1 1 the distance between the pintsIO and lit.

being short enough to permit a tire valve stem and its cover to projectthrough the rim section and be accessible from the front of the 'wheel..H-oW this is done will be readily understood by an inspection of Fig. 1in which; 12' indicates generally a quickdetachable and deinountable rimprovided with: a short andv hollow rim driving lug 13' through whichpasses a valve stem 14 carry:

ing-its cover 15, the rim" section; 9' being provided witha rim drivingaperture 16. 5

and with avalve stem aperture 17, both large enough to permit rimmounting and ft-he diso'and acting to control its vibration.

This vibration controlling means: is in two]. 7

To augment this'no'dal stiffening of the united)plate and-disc, there is; employed meansiacting to subject the; unitedplate and disc to'eonsiderable pressure, and}, as shown, this meansconsists in a series t disc mounting bolts 21 and nuts22 equal number tethe plate salients and radially anra-nged with respect thereto, or, inother wer jds, on the five nodal lines established S0 odd; numberofnodal lines and/thus divide r the peculiarQlhpc and adjacent its outerperiphery, and, as shown," these dampers, marked23, are located in theconcavity of the rim section 9 and are united therewith by'spot Weldingat Q tand 25. means of these dampers, the rim section 9' is stiffened inan odd number of positlons,
